A mix engineer is the person responsible for incorporating all the different recorded elements of music (vocals, instruments, effects etc.) to make the final version of a song. These mixing professionals have many years of experience and training with audio equipment which has enabled them to master the art of audio mixing. Occupying a place between an artist and scientist, a mixer uses their outstanding ability to hear and understand the harmonic structure of sound, allowing them to use technology to create highly appealing timbres. Their work is found in all modern music, but many artists now mix and produce their own music with a digital audio workstation and a computer.

Mixing Engineers are often formally trained in a music background, and most get a degree in audio engineering or recording engineering*. A degree in music can help and broaden the engineers credentials, though it is known that most experience comes from operating complex audio equipment. The mixing ear comes from years of observing all kinds of sounds, frequencies, and variations of effects and filters, through the process of trial and error.

Andrew Thornton is a National Hunt jockey.

He was born on October 28, 1972 in Cleveland and schooled at Barnard Castle School in County Durham. He is not related to another of England's greatest jockeys, Robert Thornton.

He rides mainly for Caroline Bailey,Seamus Mullins,Henrietta Knight,Ben Pollock and Richard Rowe.as well as for many other trainers. Thornton is one of the very few National Hunt jockeys who wears contact lenses while riding and it is for this reason that he has acquired the nicknames "Lensio" and "Blindman" [1]. He is married to Claire.

Despite having to endure many setbacks and injuries throughout his career, Thornton is now widely regarded^{[by whom?]} as one of the best jumps jockeys around. He is also very highly respected among his weighing room colleagues. His opinion on horse racing is also well sought after by members of the Racing Post, Racing UK and At The Races.

Many^[who?] criticise Thornton's riding style. However, it is quite effective in most experts' opinions. Because he is taller than the average jump jockey, he is forced to ride very low in the stirrups. It is not always attractive to look at but it rarely fails to get the job done.^{[citation needed]} Its benefits are also highlighted by the record Thornton has in staying Handicap Chases and staying Handicap Hurdles. Along with Tony McCoy, he is probably the strongest jump jockey in a finish.^{[citation needed]} He can push along from a mile out and galvanise the horse. His strength has been seen in many exciting finishes when he looked beaten turning for home.
